Our aspheric lenses are made from Schott B 270® Ultra-White Glass which has numerous advantages for condenser lenses. For example, it is highly transparent across a wide range of wavelengths, and is highly resistant to intense UV exposure, making it ideal for use with light sources such as high intensity arc lamps.

One important point to note though is that some lenses are designed for different camera bodies, so always check before making a purchase. DSLR and Mirrorless cameras are either full-frame or crop sensors. While full-frame lenses can be used on a crop sensor, a lens designed for a crop sensor can’t be used on a full frame!

Our Aspheric Condenser Lenses provide higher numerical apertures (NA), larger apertures and lower f# ratios, when compared to standard spherical lenses. They are ideally suited for illumination applications, such as light collection and condensing, projection and detection. Examples include coupling light into and out of optical fibers, efficiently collecting output from optical sources, or focusing beams onto small high-speed detectors.

Even the experienced photographer will be hard-pressed to explain the exact differences and function of each particular lens, but knowing more about the functionality, focal lengths and uses of a lens can help you to employ it in the right situation.

Our uncoated aspheric condenser lenses are fabricated out of Schott B 270® Ultra-White or equivalent glass. These condenser lenses provide excellent transmission in the visible to near-infrared regions. The aspheric condenser lens surface is molded, while the plano or spherical surface is ground and polished. Ideal for light collection, projection, illumination, detection, and condensing applications.

We offer a full range of optical lens mounts to meet various experimental requirements. Below lists the recommended mounts for spherical lenses of standard sizes. Please see our Lens Mount Guide for additional information.

In applications that require large acceptance angles, such as light gathering for illumination, spherical lenses are unsuitable due to spherical aberration, or the effect of refractive power of a spherical surface becoming greater with increasing aperture. Aspheric lenses maintain constant focal length or very high NA, avoiding the need for multiple elements to correct spherical aberration. This simplifies system design by reducing weight and component count. It also results in less transmission loss, and less ghosting due to having fewer surfaces. The primary drawback of an aspheric lens is off-axis performance is poor. This is not a problem for coupling to and from optical fibers or collimating light sources, but aspheric lenses are not usable over a wide field of view.

And knowing when to use the correct lens, is just one step towards becoming a much better photographer. In this article, we take a look at the different types of camera lenses and when they should be used.

A prime lens is a classic style that has been around as long as cameras have. Prime lenses have a fixed focal range, which means that you can't zoom in or out.

It can be quite overwhelming in the early stages of getting into photography when you find out just how many types of camera lens there are. Fortunately, camera lenses can be broken down into two types, zoom lenses and prime lenses. We’ll explain what the definition of these two camera lenses are below.

Zoom lenses are incredibly versatile, with the most popular being the 70-200 mm lens that you’ll see being used by wedding photographers. Zoom lenses have variable focal lengths, so with a 70-200mm lens for example, you can zoom from 70mm all the way up to 200mm.

Wide-angle lenses are a must-have if you’re a landscape photographer and looking to step up your game. Wide angles have a wider focal field, allowing you to essentially capture more of the scene in front of you than say a zoom lens.

In this article, when we talk about lenses we will be referring to the detachable lenses that are used by photographers. The same principles apply across different brands, be it Sony or Nikon, and across different types of camera body, be it DSLR or Mirrorless.

Telephotolens

Because of this, prime lenses produce much higher quality images than a zoom lens in general, but you will need to know in which situation you can use them. For example, the 50mm prime lens, otherwise known as the Nifty Fifty, is perfect for portraits, as the focal length is seen to be as close to the human eye as possible.

Note: besides the diameter, please check the Edge Thickness (Te) specification of the lens and the lens mount to ensure compatibility before purchasing.

If you are a professional wildlife photographer, sports photographer, or if you photograph the night sky and the stars, then a telephoto lens can be invaluable. For amateurs though, it’s perhaps not within your budget.

In conclusion, there are different types of camera lens for almost any situation you could find yourself in as a photographer. Knowing which lens is best for what scenario, will set you on your way to becoming a much-improved photographer.

For budding photographers or anyone needing to photograph in a diverse range of scenarios or conditions, there’s nothing that can really beat a good zoom range for quality and adaptability. It’s the all-round lens that everyone needs!

Telephoto lenses are bulky and may require a tripod to support them, making them nowhere near as practical as a standard zoom lens.

If you need to capture an even wider field of view, then you’ll need to invest in a fisheye lens. These create the unusual 'fisheye’ effect, similar to a GoPro image.

If a standard zoom lens isn’t quite strong enough for your needs, then the next step up is a telephoto lens. These big lenses are found within a range of 100mm up to 600mm, sometimes even more.

The main advantage of prime lenses is that they specialise in just one focal length. In other words, they are finely tuned to deliver on one specific type of photography, unlike a zoom lens which can be used in a multitude of cases.

If you’re travelling light, though, you can find zoom lenses with much more range, such as an 18 - 270 mm, allowing you to photograph both close up and in the distance.

Zoom lenses are one of the most common types of lens that you’ll need in your photography armoury, offering you a great range for photographing anything from people in the streets to wildlife in the African Savanna.

A fisheye lens is basically an ultra-wide-angle lens, offering an enormous field of view. These are more specialist lenses and aren’t generally needed by most photographers. They are useful if you are photographing indoors or using your camera for design work. An ultra-wide-angle lens can have a focal length as low as 8mm.

For this reason, wide angles are perfect for photographing landscapes, as you can capture more of the scenery and create a much more vivid picture. They are also great for photographing architecture, as you’ll be able to capture the whole building in front of you.
